Plot traces from list of chromatograms. — plot

Plots the specified traces from a list of chromatograms.

Usage

plot_chroms(
  x,
  lambdas,
  idx,
  xlim,
  ylim,
  xlab = "",
  ylab = "Absorbance",
  engine = c("base", "ggplot", "plotly"),
  linewidth = 1,
  show_legend = TRUE,
  legend_position = "topright",
  ...
)

Arguments

x: A list of chromatograms in matrix format (timepoints x wavelengths).
lambdas: The wavelength(s) you wish to plot the trace at.
idx: A vector representing the names or numerical indices of the chromatograms to plot.
xlim: Range of x axis.
ylim: Range of y axis.
xlab: X label.
ylab: Y label. Defaults to "Absorbance".
engine: Plotting engine. Either base (matplot), plotly, or ggplot2-package.
linewidth: Line width.
show_legend: Logical. Whether to display legend or not. Defaults to TRUE.
legend_position: Position of legend.
...: Additional arguments to plotting function specified by engine.

Value

No return value, called for side effects.

Side effects

Plots the traces of the specified chromatograms idx at the specified wavelengths lambdas. Plots can be produced using base graphics, ggplot2, or plotly, according to the value of engine.
